The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for wh ich a technical committee hag been established hag the right to be represented on that committee. International organizations, govern- ,-. mental and non-governmental, in liaison with ISO, also take part in the .,. work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 1207 was prepared by Technical Committee ISO/TC 2, Fasteners. This third edition cancels and replaces the second edition (ISO 1207:1983), which hag been technically revised. 8 ISO 1992 All rights reserved.
